Rick Santorum's appearance on Fox News's "On the Record With Greta Van Susteren" on Wednesday night is expected to shed light on his next steps toward a potential White House bid, possibly including the formation of an exploratory committee.

The former Pennsylvania senator has already said he plans to participate in the first presidential debate of the campaign season, one that requires participants to have formed a presidential committee first. The May 5 debate, sponsored by the South Carolina Republican Party and Fox News, will be held in Greenville, S.C.

He also announced Monday that he plans to participate in a June 7 presidential debate in New Hampshire, sponsored by the New Hampshire Union Leader, CNN and WMUR-TV.

Santorum has said that his seriously ill daughter could weigh heavily on his decision on whether or not to enter the White House race. Last month, Santorum pulled out of Iowa Rep. Steve King's Conservative Principles Conference, when his daughter Isabella – born with a genetic disorder called trisomy 18 – fell ill.

Google Santorum. It is worse than you think. Even republicans don't like him.

Consider this, during his re-election campaign for US senator in PA in 2008, Santorum (who was running unopposed), got less votes than the republican candidate for governor who eventually won the primary and was not running unopposed.

Rick Santorum should take his daughter to Canada, where she can get the health care that she's denied by American insurance company bureaucrats wedged between the Santorums and her physician, It is the intrusive American insurance company bureaucrat who is making their medical decisions and rationing her health care which she would have in without the severe restictions and insurance company rationing of the US system.
